Description
Introduction:
FB-WFL/M weigh
feeder, absorbing Germany Schenck technology
(replacing DEL/DEM scale of Germany Schenck), is perfect equipment
for continuous weighing, feeding and dosing bulk material and
powder, and the same time realizing open-loop and closed loop flow
control, our company have three models: WFL, WFM and WFS, it can be
widely used in building materials, chemicals, coal, ports,
ceramics, food, fertilizer, and other industries
System extensibility:
1.can chose star-shaped,
disc type pre-feeding device for achieving well-distributed
feeding.
2.Can be equipped with material blockage alarm to make you find
blockage in time and remove them as soon as possible.
3.According to actual conditions, different hopper and shield can
be chosen:
4.Can achieve open-loop control.
5.Open, partial open, ffull closed out casing can be chosen.
6.It can be designed and manufactured according to the special
requirements.
Features:
1. Reliable electrical weighing
device: unique structure and reliable weighing.
2. EB-DAS***0 control system, SPL-F microcomputer centralized
control system, PLC control system are optical.
3. Unique deviation- resisting technique ensures the belt operate
well.
4. Belt of different width, thickness, environment suitability can
be chosen according to specific process requirements.
5. Unique spillage-proof device.
6. Unique belt tightening and aligning device.
7. Unique scraping device to protect belt and make the system
operate well.
8. Sophisticated weighing system, no operation friction and with
little maintenance.
9. Installation load cell is treated specially to protect the load
cell and ensure stable and reliable long-term operation.
*0. High accuracy speed measuring device is the effective guarantee
for system measurement.
*1.Unique electrical automatic calibration, captive chain
calibration, and weights-hoist calibration.
Working Principle:
The working principle of
belt conveyor is installed the Electrical weighing device under the
belt, when the material works on the
load cell which can generate a signal in proportion to the material
weight and the signal is transmitted to the controller. At the
same time, the speed sensor installed on the tail pulley detects
the belt speed and generates a signal which is also transmitted to
the controller. By multiplying the weight signal and the speed
signal, the instantaneous
flow rate and total accumulation
can be calculated.
